The electrons enter a 2.0 cm long gap between the two parallel plates where the electric field intensity is 5.0×104 N/C down. See the diagram below. a) Determine the time to cross the plates. b) Determine the magnitude and direction of the acceleration in the region between the plates. c) Determine the final velocity of the electron as it leaves the plates (both magnitude and direction).

You are working on a research project in which you must control the direction of travel of electrons using deflection plates. You have devised the apparatus shown in the figure below. (i) The plates are of length ℓ = 0.750 m and are separated by a distance d = 4.95 cm. Electrons are fired at vi = 5.50×106 m/s into a uniform electric field from the left edge of the lower, positive plate, aimed directly at the right edge of the upper, negative plate. Therefore, if there is no electric field between the plates, the electrons will follow the broken line in the figure. With an electric field existing between the plates, the electrons will follow a curved path, bending downward. (a) Determine the range of angles (in degrees) over which the electron can leave the apparatus. (Assume θ is measured counterclockwise from the +x-axis. Enter your answers as a comma-separated list from smallest to largest. Do not enter units in your answer. ) (θmin, θmax) = ( )。 (b) Determine the electric field (in N/C ) required to give the maximum possible deviation angle. (Enter the magnitude.) N/C

An electron is projected with an initial speed v0 = 1.70 × 10^6 m/s into the uniform field between the parallel plates in ( Figure 1). Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Electron in a uniform field. Figure 1 of 1 Part A If the electron just misses the upper plate as it emerges from the field, find the magnitude of the electric field. Express your answer in newtons per coulomb. Part B Suppose that in the figure the electron is replaced by a proton with the same initial speed v0. Would the proton hit one of the plates? yes no Part C If the proton would not hit one of the plates, what would be the magnitude of its vertical displacement as it exits the region between the plates? Express your answer in meters. Part D What would be the direction of proton’s displacement? displacement is upward displacement is downward
